Abstract

Examination of the late Cretaceous-early Tertiary succession in Taramsa section, West of Qena, has revealed the presence of latest Maastrichtian fauna and nannofossil flora. The distinct biotic changes at the Cretaceous/Tertiary boundary characterize a profound environmental instability. The gradual replacement of the Cretaceous taxa by Tertiary ones suggests a transitional character of the boundary. The marked change in colour and the observed variation in lithology near the Cretaceous/Tertiary boundary do not indicate, at the present time, whether the sedimentation was contineous or contain a hiatus at the boundary.
